Linux – How to use webex from Debian Linux

Colleagues have scheduled an important presentation on webex with> 20 participants for tomorrow.

Requirements

I get a message that my browser is not supported when I try the webex test meeting. There seems to be 2 lists of requirements:

• The webex meeting suite requirements Firefox 32 bits only there.
• The list of Web App Supported Operating Systems and Browsers. Firefox on linux appears there.
  I don't know which one applies to my meeting type?

32 bits Install instructions only

The only instructions from webex I found are these ones on help.webex.com: How-can-I-Join-a-Meeting-Using-64-bit-Red-Hat-Linux-6.
The help page suggests installing the following:

• Download 32-bit Mozilla Firefox: http://www.mozilla.com/en-US/firefox
  • Install 32-bit Mozilla Firefox
• Download 32-bit Adobe Flash tar.gz for Linux package: http://get.adobe.com/flashplayer/
• Download Sun JRE Linux Self Extracting file: http://www.java.com/en/download/manual.jsp
• Ensure the following i686 rpms are installed:
  alsa-lib.i686
  dbus-glib.i686
  glibc.i686
  gtk2-engines.i686
  gtk2.i686
  libcanberra-gtk2.i686
  libcurl.i686
  libXt.i686
  nss.i686
  PackageKit-gtk-module.i686
• etc…

I am very surprised that it still uses flash and so many 32 bits applications.
We are in 2020. Is there really no other way for me to listen to this webex presentation?
